Y., A CORPORATION OF NEW JERSEY Application led May 26, 1923, Serial No.641,702, and in France May 30, 1922.

My invention relates to a radiator adapted for hot water or steamheating of rooms, and so arranged as to be constructed with the minimumsize and Weight while possessing a sufficient strength to support shocksas well as an attractive appearance, it being analogous to a piece offurniture.

In order to comply with these various conditions in a simple andeconomical manner, the invention consists in the construction of aradiator body having thin walls and wherein the strength and appearanceare made subsidiary to the question vof light weight and the relationbetween general size and radiating surface, combined with an outerenvelope of a more or less decorative character which serves as aprotection against damage as well as to conceal said radiator body, andwhereof certain parts, and especially the lateral portions, areconstituted by radiator elements having sufficiently thick walls andconstructed chiefly with a view of obtaining a suitable strength and anattractive appearance.

lVith this combination it becomes an easy matter to provide a heatingdevice of greater output and less expensive construction for a givensize, than in a device wherein a thinwalled radiator body is coveredwith a simple envelope or casing whose walls do not produce heat, and inwhich the construction is always expensive should the device be requiredto have an ornamental or esthetic character.

The accompanying drawings show by way of example two forms ofconstruction of a radiator according to the invention.

Fig. 1 is an elevation, partly in section, of a radiator adapted formounting in the middle of a room, and,

Fig. 2 is a side view of the saine in section.

Fig. 3 is a plan View ofthe same radiator partly in section.

Fig. 4 is an elevation of a portion of a modified form of radiator withthe front plate omitted,

Fig. 5 is a transverse section of the same; and

Fig. 6 is a plan thereof with the top omitted, parts being in section.

In Figs. l to 3, 1 indicates a radiator body vwhich is shown in adiagrammatic manner and which iii principle requires to be protected andconcealed. Adjacent the said body l are disposed two cast iron radiatorelements 2 which are connected with the ends of the body by suitablemeans and are also cross-connected by rods or braces 3. The two vmainsides of the body l are protected by sheet or cast metal plates ll-, 5secured to corresponding ribs of the elements 2, preferably in aremovable manner ing the said main to provide for cleanbody. rI he saidplates may be plain or apertured, or if required, embossed or stamped orprovided with separately attached mouldings or ornaments. rlhe main bodyis covered by a top cover 6 which is preferably apertured for the outletof hot air and may be made in one or more pieces.

The inlet and outlet pipes for the heating Huid 7 and 8, are secured toone of the elements 2 or to both these elements as desired, either atthe side as represented, or at the back of the radiator so as to concealthe piping and valves as elements may be section and may manner providedmuch as possible. The said given any suitable crossbe constructed in anydesired the outer faces have suflicient strength and an appearance suchas will be in harmony with the it is placed.

to 6 is adapted wall; the plate to be mounted against the 5 adjacent thewall is provided with an insulating covering 9 and may be polished atwith a facing w lwards the interio the outer part or provided forms areflector tothe room whereby rahich r of diation towards the wall shallbe reduced `as much as possible.

of the radiator l is shown in this case as composed of a set of tubularcast iron elements having a small thickness and large radiating surfaceand secured togo ai gether as in known cast iron radiators, or by likemeans. The elements 2 which are secured tothe end elements of said mainbody will have thicker walls, if required, and their external faces maybe plain or provided with mouldings or like ornamental parts obtained'bycasting,'or maybe coinposed of separate tubes.

The plate 4 is secured tothe ribs 1l of the elements 2 by Ysuitablelocks la4 or by like means providingfor the readyV removal of .saidplate for cleaning purposes, and in this event the elements 2 willextend forwardly of the plated by a certainfamount so as to afford theappearance of the uprights of a piece of furniture.. The opposite. platemay be seeuredand. disposed in the same manner as the; preceding, orotherwise.

4The top cover 6v is securedV by screws l2 the lugs 13 of the elements2, and to provide `tor yany slightly variable distance between thelatter it is advisable in order to facilitate the mounting to render atleast one of said lugs adjustable, it being for example.` constituted byinto the element 2,the head being provided with a screwthreaded holeadapted to .receive the sore-w12'r Aso 16 so inclined asV to directarranged Vor grouped In order to increase the output of the apparatus itmay be advisable Vto dispose at the interior and between said tubeelements aset of sheet metalplates 14, fiat or corrugated, which areAattached for example to the plate 5fand: become heated byY ing the airby convection.

`In the example shown in Figs. 4 to 6, an opening l5 is. made atA thebottom of the wall for the inlet of `cold air, and the lower part `oftheradiator is provided with a deflector air to the centre ofthe room.Obviously, the

use of this latter arrangement is optional.

The body of said radiator which it is desired t conceal" and protect mayof course be made of any suitable types of elements such as flat plates,tubeswith or without radiating iianges, worm. tubes, and-the like, whichare in any desired manner. lfaims: Y l.
